STARTING, GENERATING, AND IGNITION APPARATUS.

Application filed .Tune 29, 1917.

To all whom it may concern Be it known that I, lVILLIAM B. Moses, acitizen of the United States, and resident of Brookline, in the countyof Norfolk and State of Massachusetts, have invented certain new anduseful Improvements in Starting, Generating, and Ignition Apparatus, ofwhich the following is a specification.

This invention relates to starting, generating and ignition apparatusfor engines, and with respect to certain more specific features thereofto such apparatus forautomobile engines. It has special applicability toFord automobiles.

One ofthe objects of the invention is to provide apparatus of thecharacter above mentioned, which shall be simple in construction, easyto install and durable. I

Another object is to provide improved means whereby an ignition unit maybe as sociated with starting and generating units in a compactorganization, which latter is adapted in turn to be attached to anautomobile engine Within the limited space available.

Still another object comprises the provision of reliable and inexpensivemeans for securing and maintaining certain parts of the apparatusassembled and in operative relations, while" nevertheless permittingtheir detachment in a quick and convenient manner. 4

Other objects will be in part obvious and in part pointed outhereinafter,

The invention accordingly consists in the various features ofconstructitm, comb-inai n o l m nts an ."1.-ang 1,1;1 1.1 s o par swhich will be exemplified by the n u tion. hereinafter set forth and thescope of h application of whi h i l be indicat d in h following claims.

Fig. 6 is a right side elevational view with parts in section of theline 66 of Fig. 1.

Referring now more particularly to the drawings wherein similarreference characters refer to similar parts throughout the several viewsthere is indicated generally at 1 a Ford engine comprising a wateracketed cylinder casting 2, with inlet pipe 3, a cylinder head casting4, Wit'h outlet pipe 5,

and a crank case 6 with extending nose or snout 7. The forward end ofthe cylinder block or casting 2 is formed to provide a flanged timinggear housing 8 and the present standard Ford engine has associated withthis housing a cover plate, which for the purposes of this invention maybe discarded.

In accordance with the rules reference is made to my co-pendingapplication for United States Letters Patent for improvements instarting and generating apparatus, filed March 30, 1917, Serial No.158,541

Referring now to Figs; 1 and 2, it will be noted that a supporting plateor bracket 10 issecured forwardly of the engine and trans.- versely ofits crank shaft 11. The attachment is made at points around theperipheral flange of the timing gear housing by removing thebefore-mentioned timing gear cover plate and bolting the bracket 10 inplace thereof. Other points of attachment are provided at the base ofthe bracket in the form of lugs having bolt holes positioned to registerwith standard points of attachment between a flange of the cylindercasting d a cor esponding fl ng 'th rank case- A t mingshaft 1,2 i d ivn in the usual way from a g a on the crank haf a gear twi e s z on thetiming sha t The e g ars. are uita ly incased. t run in oil in th using;8-. he bra ket 1, is p ovided Q11 on side with means or adjustablysecuring a motor unit 13, and on the opposite sid the bracket i providedwith milar means. for adiustably wr-ina a g n rating unit .4, the mean,con'mri ne inoth nstances, S t of bolts 1'5 two of which pa s throughslots 16. in the bracke 1 an n into. th

The bracket 10 is provided with a substantially large circular opening17, Which in assembly position, is concentric with the timing shaft 12.The bracket is also apertured at 18 concentrically with the armatureshaft 19 of the generator unit, and a filler spout 20 is provided,suitably shouldered to engage the bracket 10 at the opening 19 andnormally close the same. This filler spout is held in place by a springfinger 21 pivotally mounted on the bracket 10 so that it may be swunginto and out of engagement with the spout, as desired.

Referring now more particularly to Figs. 1, 2 and G, the crank shaft 11has secured thereto a pulley 23 which is formed with a wide laterallyextending flange 24. To this flange are bolted web portions of a spurgear 25, this gear being preferably of as large a diameter as ispossible to fit into the nose or snout '7. The pulley 23 is connected bymeans of a belt '26 with a fan pulley 27, whereby the engine fan isdriven directly from the engine crank shaft. Means are provided in theform of an adjustable stop and a lever arm 28, which serves as a supportand bearing for the fan shaft, for increasing or decreasing the tensionon the belt 26.

The power transmission from the. motor unit to the crank shaft is asfollows: (Figs. 1, 2 and (3:) On the end of the armature shaft 30 of themotor there is fixed a sprocket 31 which is connected by means of achain 32 with a sprocket 33 formed on a sleeve 34, which sleeve isjournaled in the bracket 10. l/Vithin the sleeve'3l, there is mounted acounter shaft 35 having a threaded portion 36 upon which is mounted forrelative longitudinal movement'an unbalanced pinion 37. The shaft andsleeve 34 are yieldably connected together by means of a torsion spring38, one end of which is connected to the sleeve 34 by a bolt 39, theother end of which is connected to the shaft 35 by a bolt 10. Thetransmission parts are soarranged that when the motor is energized," thesprocket 33w'ill be driven from the sprocket 31 rotating the sleeve 34and through the yielding connection just described turning thecounter-shaft 35 at a "ate of speed suit able to cause the pinion 37 tomove longitudinally along the threads 3(3 until the teeth of this pinioncompletely engage with the teeth of the gear 25 and until the pinion isobstructed in its longitudinalmovement by a stop 41 whereupon it willturn with the counter shaft 35, rotating'the gear 25 and give the enginecrank shaft the initial move ment required.

Movement of the crank shaftunder the engine fifel will zultolmiticallyreturn the pinion 37 to"no'rmal position of disengagement with the gear25 and the motor being de'energizcd will remain at rest. Through thetiming gears, however, as is well known, the timing shaft is rotated atone-half crank shaft speed. By the substitution on the timing shaft 12of a sprocket 45 for the standard lock nut therein employed means areprovided for driving through a sprocket chain 16 a smaller sprocket 17keyed to the arn'lature shaft 19 of the generator unit, whereby thegenerator armature may be rotated continuously from the engine atcomparatively high proportionate speeds. The generator unit 11 isformedwith a substantially wide end cap member 18 recessed at 49 to receive aspirally toothed ignition shaft driving gear 50, this gear being keyedto the generator armature shaft 19 adjacent the sprocket 17. The end cap18 provides a journal 51 for the main vertical shaft. on an ignitiondevice 52. As seen in Fig. 3, this shaft is provided with a spirallytoothed gear 53 which meshes with the gear 50, providing the drivingconnection, whereby the main shaft of the ignition device is driven indirect proportion to the armature shaft, and likewise, therefore, to theengine shaft. It will be noted that the removable filler spout 20 isadapted for attachment opposite the end of the armature shaft, whichprovides for lubrication of the ignition and generating powertransmitting devices by the oil introduced for cylinder lubricatingpurposes. Furthermore, the spout being removable permits access to theend of the generator armature shaft. for purposes of assembly or removalof the parts. The innor faces of the bracket 10 serve as conduits forthe lubricant introduced through the filler spout and complete the oilpassage between the ,filler spout and the engine casing, a suitableoutlet being provided at the rear of the bracket where the same attachesto the timing gear housing of the cylinder casting.

Tn assembling the apparatus, the standard Ford crank shaft pulley may beremoved "andthe combined pulley and gear 23 and respectively,substituted. The original commutator, roller arm, timing gear. lock nutand'timing gear housing cover may be removed and the bracket 10 securedin position, after which the large sprocket 15 is screwed on to thethreaded end of the timing shaft 12 in place of the standard lock nut.Apcover plate oosuitably shouldered is then fitted into the aperture 17in the front of the bracket and thisplate is providednyith packingadapted to fit'tightly; around a hub 56 tirttlre large sprocket' Theoriginal rel-a commutator parts are then restored to with thespringfinger 21. The commutator" cap 57 bears against the outer face of theessee].

cover plate 55 and in turn seals the same in quick detachable relationwith the bracket 10.

The easy accessibility of the working transmission parts is one of thefeatures of the present invention. By swinging the fingers 58 and 21 outof engaging positions with their respective arts, the filler spout 20,commutator cap 15 Ford roller carrying armand cover plate 55 may bequickly removed from the assembly giving free access to the chain andsprocket connections of the generator drive. If it is desired to removethe generator unit for any reason it is only necessary to remove thefiller spout and the sprocket 47 may be withdrawn from the generatorarmature shaft from the front of the bracket through the openingnormally closed by this spout. The generator and ignition units may thenbe removed by freeing the bolts 15 from the end cap 48. B this means itis not necessary to open the sprocket chain46 or remove same from eitherone of its sprockets.

It should be noted that the various parts described have multiplefunctions whereby the exceptional compactness is obtained and theapplication of power confined to points of exceptional reinforcementagainst lateral stress. The bracket 10 not only performs a supportingfunction but is hollow and shaped to serve in the oil conduit from thefiller spout to the lower crank casing. And so, as well, does thebracket serve as a housing forthetransmission parts, enabling them topartake of the cylinder lubricant passed through from time to time andpreventing the ingress of dirt. Further, the bracket serves to incasethe timing gears, and disregarding the motor side for the momentbecomes, in short, a cover'plate for the timing gear housing of theengine casting, with but a short lateral extension to receive thegenerator. This extension comprises a hollow chamber with an opening atthe rear to communicate with the coupling or end-cap member and anopening at the forward side to which is fitted the filler spout.Obviously as far as the oil filling features are concerned, the dynamomight be attached directly to the rear wall of the bracket withoutincluding the coupling or ignition member.

It will be found that the member 48 performs several services. Itcarries the igniter shaft properly journaled, provides for attachment tothe rear wall of the bracket and to a forward part of the dynamo frame.It provides a housing for the driving connection-between the armatureshaft and the igniter which housing is in communication with the oilconduit formed by the bracket permitting the passage of oil to saidhousing for lubrication of the driving connection. The mounting of theigniter, as shown herein, at a point in close proximity to the point ofattachment of the generator unit to the bracket, has an important effectin minimizing vibration.

As many changes could be made in the above construction and as manyapparently widely difi'erent embodiments of the invention could be madewithout departing from the scope thereof, it is intended that all matterset forth in the foregoing description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.
